How our drinking water could come from thin air (www.bbc.com)

Southern Nevada is in the grip of one of the worst droughts it has experienced in recorded history, leading to water shortages and restrictions on use. So, in water-stressed areas such as this, the prospect of wringing water from thin air is an appealing prospect. And it is exactly what Cody Friesen is trying to do.

Friesen, an associate professor of materials science at Arizona State University, has developed a solar-powered hydropanel that can absorb water vapour at high volumes when exposed to sunlight.

It is a modern-day twist on an approach been used for centuries to pull water from the atmosphere, such as using trees or nets to "catch" fog in Peru, a practice that dates back to the 1500s and is still being used today.

That's a logical assumption. It says here that "The SOURCE Hydropanels are already being used by schools in Mexico, Syrian refugee communities in Lebanon and Jordan, and fire stations in Puerto Rico that have been hit by hurricanes" which, if true, shows possibility for wider application where needed.
